During each heartbeat, your right ventricle pumps blood to your lungs to exchange carbon dioxide for oxygen.
Your left ventricle pumps blood through your aorta to the rest of your body. While this is happening, your atria fill with blood and then move it down into the ventricles to get ready for the next heartbeat. Blood moves into your ventricles in between each heartbeat. The premature beat may feel different from a normal heartbeat because little or no blood is being pumped out of your heart.
If your ventricles have had time to fill with blood, the premature beat will be more noticeable. But if the premature contractions are an ongoing problem, bigeminy can be a sign of heart trouble down the road. You may not even be aware that premature contractions are happening. These may be mild, or they may make you feel acutely aware of how your heart is beating every moment. If you have bigeminy, you may feel that your heart is beating too fast or that your heart is skipping a beat.
Other potential triggers of premature contractions include:. The main test to diagnose bigeminy is an electrocardiogram EKG. In an EKG, your doctor will place electronic sensors on your chest.
These sensors painlessly record the electrical activity in your heart. The recorded information reveals the pattern of your heartbeats and can often identify the source of the unusual heart rhythm. You may also undergo what is called an exercise stress test. This can help your doctor determine the severity of your bigeminy.
Share on Pinterest The cause of bigeminy may not always be clear, since there are many possible causes. Diagnosis and when to see a doctor.
Treatment and lifestyle changes. Share on Pinterest Avoiding coffee, tea, and other drinks containing caffeine may help to treat bigeminy. Exposure to air pollutants may amplify risk for depression in healthy individuals. Costs associated with obesity may account for 3. Related Coverage.
